YANKTON, S.D. (AP) - Officials said a bird poison used at a feedlot apparently caused a die-off of birds at Yankton.
Yankton Animal Control Officer Lisa Brasel said DRC 1339, a bird poison used by the U.S. Department of Agriculture, was the likely cause of death for more than 300 starlings found in the downtown area.
Brasel said a USDA official contacted her after seeing new reports about the dead birds.
In an interview with the Press & Dakotan newspaper, wildlife biologist Ricky Woods confirmed that the poison was used by the USDA at a feedlot about 10 miles south of Yankton. He said birds usually die before getting so far from the poison.
